In the not so distant future, there came a point in time when mankind had waged war with itself to the point of certain extinction. The scant number that survived the self-genocide were left with an ultimatum: Devise a new way in which to live in peace or face destruction. Among their wisest leaders stepped forward a man who claimed to hold the key to their salvation. He was known as Prime Vonn. He shared his vision of the future. A place where the human race could live in peace and prosperity, away from the molestations of war. For this gift of emancipation, he asked for only one thing in return: the people’s unquestioning loyalty and obedience.... Enter Sanctum-One. A place where all could thrive under the wise leadership of Prime Vonn. Shielded and protected from the natural sins of man, it slowly became a shining example of how civilization should have conducted itself from the very beginning. At last, the sons and daughters of a bygone era could flourish into a golden age where anything was possible.... But it was all a lie. A smokescreen where mankind’s savior was, in fact, her cruel dictator; seizing control of her free will with the aid of his Inner-Sanctum. A secret organization extricating anyone who sees through the veil of distortion Vonn has blinded his citizens with. Enter Lex. Betrayed by the lie she’d sworn to protect, she’s left with nothing but the will and determination to find those responsible for the death of the one person she cherished most in the world. One of the few who knows Sanctum-One for what it really is and fueled by an all-consuming rage, she wreaks a one-woman rampage across Sanctum-One, one high-ranking official at a time. To Vonn’s Inner-Sanctum, she is known as "The Woman". And she will have her vengeance. She will have her retribution.She will have her revenge.
